Symptoms of a Bad or Failing Air Diverter Valve

The emissions system of a car has many different parts that help to reduce the amount of pollution the car emits. The air diverter valve helps to put clean air into the system to push out pollutants, without letting the exhaust fumes out. This part works in conjunction with the air bypass valve and in most cases they will have to be replaced as a pair.

Many states have strict regulations regarding the emissions of the cars that are allowed to drive on their roadways. These strict regulations are just one of the reasons why keeping your car’s emission system in check is important. Having bad emission components can lead to your car letting off more harmful exhaust fumes. The last thing that you want is to be fined for emissions related issues due to neglecting to replace a bad air diverter valve.

1. Car is running rougher than usual

Among the most noticeable signs that the air diverter valve is damaged is your car running sluggishly. The air/fuel mixture of your car is very important in keeping it running smoothly. Having a bad air diverter valve will throw this mixture off and cause the car to run and idle rough. Not having the full power of your engine when operating your car can create a lot of danger when trying to navigate the roadways so it is recommended that a professional mechanic replaces the failing air diverter valve.

2. Gas mileage is suffering

One of the biggest expenses that most people have is the monthly gas bill for their car. Getting good gas mileage is an essential part of saving money, but nearly impossible when you have a broken air diverter valve. The broken valve will cause the fuel to mixed too lean, which in turn causes a lot of gas to be wasted.

3. Check Engine Light is on

Another very common sign that you will notice when there is a problem with the air diverter valve is the check engine light being on. The onboard computer system that is built into your car will be alerted of the issues with the air diverter valve and will turn the light on to warn you. Getting the light checked will give you the answers you need to get the appropriate repairs done.
